The all-round zoom lens• With an effective focal length range of approximately 29 - 216 mm (in relation to the 35 mm format), the EF-S 18-135 mm 1:3.5-5.6 is ideal for most shooting situations. Whether wide-angle for landscapes or telephoto for sports day, the EF-S 18-135 mm 1:3.5-5.6 is ideal for all your needs.Optical Image Stabilizer• The Canon optical Image Stabilizer (IS) integrated in the lens enables up to four times longer shutter speeds: ideal for use in low light conditions when a tripod cannot be used. The Image Stabilizer reduces camera shake for brilliant images.High-speed autofocus• A new DC autofocus motor combined with a fast processor and an optimised AF algorithm provides a fast and accurate autofocus function.Super Spectra coating• Canon's Super Spectra coating minimises the flare and ghosting that often affects digital cameras due to reflections off the image sensor. The optimised lens coating minimises flare and ghosting and ensures excellent colour balance and pin-sharp contrast.Atmospheric bokeh effect• A circular six-blade aperture delivers an attractive bokeh effect. Creatively blurring background detail makes the main object even more striking — this can be used to make portraits more attractive.
